To all 'wiwm may concern.' Y

Be it known that I, RAY H. \MANsoN, a citizen of the United States, residing at Rochester, in the county of Monroe and State oNew York, have invented certain new and useful Improvements in Radioplugs, of'which the following is a full, clear, concise, and exact description.

rlhe purpose of this invention is to ro l@ vide an electrical connection. plug in w ich the parts are easily accessible and to which various types of terminals of electrical conductors may be easily connected.

The main feature-.of this invention resides l in the manner of mounting the binding posts as well as in structure of the body portion of 'the plug whereby all strains are removed from the binding posts and the electr1cal conductors whenever the plug is inserted 1nto, or removedfrom, the jack with which 1t is adapted to co-o erate.

An additional sature of the invention is the method of attachi the stay cord to the handle of the lug, W ereby the two portionsof the han le may be opened on the stay-cord as a hinge to permit easy removal of the lu assembly.

In. t e rawings Fig. 1 represents a side view of the plug. Fig. 2 represents a side view of the plug with one portion of the handle removed to expose the arrangement of thelug assembly within the handle. Fig. 3 s ows a view o one half of the han die of the plug. Fig. ,4. shows a view of the plug assembly with the piece parts thereof separated in order to more clearly show the relation of the parts. Fig. 5 is a sectional view taken on the line 5-5 of Fig. 1. Fig. 6 is a sectional view taken on line 6-6 of m Fig. 2 looking in the direction of the arrows. Fig. 7 shows the method ofmounting the stay cord'in the two portions of the handle of the plug. Fig. 8 shows an end view of a part oi" the body portion of the plug. Referring to the drawings, the plug consists of a plug assembly designated 10 shown in Fig. d with its parts in spaced relation, and the handle generally designated 11. By reference to lfig. d it will be seen that the @9 plug assembly consists or a hollow body por tion12 with spaced shoulders 13 and it, the shoulder lll having portions slabbed oli as shown in litig. 8. tube oil insulating material 16 lies within the body ortion 12 to electrically separate the tip ro 17 from the body port1on of the plug. It should be noted at this time that the tip 18 and the tip rod 17 are integral thus insuring that these parts will not become separated in use, asis the case when the tip is screwed to the tip rod. insulating washers 15 separate the tip 18 from, the body portion 12.

Binding posts 19 and 20 are located at the lower end of the plug assembly. The binding post 19 has an apertured extension 21 which engages the lower end of the body portion 12, and it also has shoulders one of which engages the slabbed portion ofthe shoulder 14. The opening in extension 21 is of such dimension as to receive the lower end of the tube 16, so that binding post 19 is well insulated from the tip rod 17. It should here be noted that each of the binding posts 19 and 2O are provided with a second opening 22 to receive a pin terminal or even a large sized wire or electrical conductor while a screw such as 23 threaded into the end of the binding post has its end extending into the opening 22 to hold `such pin terminal wire in electrical engagement with the binding post. In the event that it is desired to use spade terminals or wires of smaller size for the conductors, they may be em secured to the binding post by placing t between the head lof screw 23 and the end of the binding post. lt will thus be seen that plain conductors of several different sizes as well as pin or spade terminals of such conductors are adapted to be engaged by the binding posts. )The structure oit binding post 20 is substantially similar to that of binding post 19 except that the opening in its extension 24. is smaller than that in extension 21, since thisv openi is only large enough to receive the threa ed end of the tip rod 17. Square washers 25 separate binding post 20 from binding post i9 yand their square sides engage a shoulder on each of the binding posts 19 and 2O so that `when the parts are assembled in the manner indicated in Fig. 2 with the nut 26 tightened on the threaded portion o1 the tip rod il?. the binding posts 19 and 20 will be securely keyed together. rlhus there isf-no possibility l of getting the parts out ot adjustment by W5 rough usage.

' The handle of the plug consists of two parts 26 and 27 of molded composition with the interior thereof formed in the manner indicated in Fig. 3 to receive the bindin posts andto provide channels 28 by whic electrical conductors are extended to the binding posts. The two ortions of the handle are provided wit semi-circular openings 29 which register to engage the portion of the body member 12 between the shoulders 13 and 14. These shoulders thus engage the two halves of the handle so as to take the thrust in bothl directions without putting any strain on the conductors or the indin posts. The two halves 26 and 27 of the andle as well as the plug assembly i are held in fixed relation by the screw .30,

materi passin through opening 31 in one portion o the handle to engage a round nut which is placed in an opening in the other half yof the handle. This round nut ma be staked as shown at 33 of Fig. 2. The an- Adles are also provided withadditional aligning openings 34 to receive the stay cord such as 35.. By reference to Fig. 7 it will be noted that when the screw 30 is removed, the two portions 26 and 27" of the y-handle ma be opened to ex ose the lug assembly an the terminals o the con uctors, using the lstay conductor 35 as a hinge.

It will be understood that there may be many variations in the details of construction of this plug which are within vthe scope of the appended claims, without departing from the spirit of the present invention.
